Bluetooth SMD Module - BC127

Description: This is the BC127, a highly flexible, low power, small form factor Bluetooth Version 4.0 Certified Audio module. Each module comes preloaded with BlueCreation Melody software, and is ideal for developers who want to quickly and cost effectively integrate Bluetooth functionality into a project.

The BC127 module is equipped with an integrated antenna and is able to run all Bluetooth stacks and codecs at low energy and power consumption (3.3V - 4.7V and 15mA). These modules have an maximum operating range of 30m, a maximum data rate of 3Mbps, and a frequency band of 2402MHz to 2480MHz.

Hi all, I am an amateur radio buff trying to build a bidirectional bridge to add a wireless head set / mic to my mobile radios. AKA I need bidirectional audio support between 2 modules. I want to connect a off the shelf headset with boom mic to one module. The other to connect to mic input and mono audio out on a amateur radio. could these modules handle this? The ability to send a Push to talk sig from head set to radio would be a big plus as well.

Question:
I intend to use the I2S out from BC127 from the to connect to a separate hifi DAC of my choice. Can I access I2S do this directly without further configuration of the module? I would like to stream audio from my iphone to the remote DAC.

I have one question…. having bought a breakout board, I have realized this is TINY! compared to bluegiga’s ble112(which btw comes short to bc127)…. how do I solder this to a prototype pcb? Pins are way too tight… anyone got any advice?

Yeah but that’s for general SMD soldering… but these pins are too tight together to just use the hot air rework station which I normally use with small components… but I’m just afraid of ruining these small components… since they’re not cheap at all… A soldering oven maybe? but would a regular convection toaster oven work? lol…

Can this be used with both 3.3V and 5V Arduinos (or other controllers)? Both a 3.3V and 5V Pro Mini are used in the hookup guide. The supply voltage in the BC127 datasheet is listed as 3.3V to 4.7V, so 5V should be fine, right? I wanted to ask because the RN-52 Bluetooth module that is also sold on a breakout board by Sparkfun is very specifically only a 3.3V chip, so I don’t know how strict that is with this one.
